I strongly disagree.
DMS is an outdated format, and can produce more errors. (the infamous errdms readerror)
This was fine back in the BBS-Days for archiving, but nowadays it's pointless, with Terabytes of HD-Space and Gigahertz's of Computing Power.
I did my first Disk-Backups with dms also, just to convert them later to ADF. And had to dump a few again, because of the mentioned errors.
Also the TOSEC project uses ADF's for archiving.
So please use ADF instead, really! Because even thousands of ADF-Diskimages uncompressed fit easily on a 4-8GB CF-Card

I guess I'm just old fashioned that way. (:

I use dms all the time and can't say I've had much (if any) trouble with it. But if it's unstable like you guys say then sure, adf is way better. Personally I'm sticking with dms since I don't have tb's of hd space and don't really care what tosec's doing. (:

But that's me!

Edit: Just wanna add that I don't mean any disrespect towards tosec by saying what I said above, it's just not my thing.
